no pics yet, depends on your track and the events you run.
Our tracks down here aren't heavy on the tech side however i remember racing in NJ the tech was f'n hard on everything.. so ill pass tech plus u cant even see the spacer with the wheels i got once its bolted on.
I have one prostar on teh car now and my spacers are on the way.
EDIT: when you balance them be careful not to put sticky weights on the insde of the rim. My spacers came tonight and the skinnes are now on the front but I had to remove the weights as they were hitting hte caliper.
the tires come today, i'll try to get them mounted sometime this weekend if i have time at my buddy's tire shop yeah we're going to use those metal clip/bang-on deals that go on the edge of the rim instead of the inside of the rim.
tires now mounted on the rims got that done tonight at my friends shop after hours. Sometime this week i got to bolt them up to the car make sure their still good or if i need grinding.
sweet man the only thing im still worried about is hoping the clip on weights on the lip dont hit anything and also for some reason my two rear et streets required a lot of weight to balance them out was weird, the fronts didnt require much maybe like an ounce but i think the rears were both 4 ounces exactly. they had 30psi in them when getting balance not sure if that effects it or not. hmm
No pics forgot my camera did it during lunch, put on all the tires bolted em up and went for a drive everything seems to be A-OK! Looks pretty cool too.
Summit Stars w/ MT's all 4 w/ 1/2 spacer in front, no grinding. I'll get photos and post em when i go racing in the next week or two.
